To work with OpenCore 0.6.2 config.plist file you have 3 options:
- Plain text editor
- Plist file editor (I use ProperTree, attached)
- Mackie100's OpenCore Configurator, must be the latest version 2.15.00, which is the only one that handles OpenCore version 0.6.2.
The image you attach seems made with an app that for any reason does not handle your OpenCore 0.6.2 config.plist and it tries to put DummyPowerManagement as in 0.6.1, that is why you do not appreciate the changes made although really you have the Emulate section well built but it continues existing a DummyPowerManagement key in Kernel / Quirks.
This is how I see your file with ProperTree:

This is how I see it with OpenCore Configurator 2.15.00:

This is how I see it with a text editor:

We just must delete DummyPowerManagement from Kernel / Quirks so that everything is in order. I return you the config.plist file with that key deleted, now it is suitable for OC 0.6.2 and should not show an error message when starting the computer.
